CVE-2019-17211

CVE-2019-17211 affects Arm Mbed OS 5.14.0 CoAP library. The overflow occurs in sn_coap_builder_calc_needed_packet_data_size_2 when computing memory for a CoAP message: returned_byte_count and payload_len are uint16_t and their sum can wrap around, causing insufficient buffer space. Documents conf...
